HSP56 Modem under Windows XP locks Phone line at windows Start up

I hope someone has come across this problem? This is a new clean installation of XP onto a existing PC that was running Windows 98 (no changes to the hardware have been made)

The modem was recognised along with all the other hardware on the system on installation of XP and the windows generic drivers installed.

However on trying to log on I get an error 680 " There is no dial Tone" On checking the phone line I found that the dial tone is present until I get the XP log on screen, then it is silence on the line. I have tried uninstalling & changing drivers to no avail. I have tried using Modem Doctor Which indicates that there is basic comunication between Windows and the modem but flags up a RLS error where there is a connection when there should not be one. I am at a loss as to, is this a fault on the modem or something that has gone amiss in the windows installation. (The modem is currently turned off in device manager)

Any idea?

Also what Version of XP did you install? XP? XP SP1? XP SP2?

Thanks for reply, Jephree will follow up on your ideas

XP pro installed with SP2

At the moment I am having to use a frends PC to connect. So if you have any more ideas it may be a week before I can get back with the state of play
